NATURAL ORDERS. 123 



these evidently belongs to Passalia, an unpublished genus 

 in Sir Joseph Banks's herbarium, and described in the 

 manuscripts of Solander from a plant found by Smeath- 

 man at Sierra Leone, which is perhaps not specifically 

 distinct from that of Congo, or from Cer anther a dentata 

 of the More d'Oware. But Ceranthera} which M. de 

 Beauvois, being unacquainted with its fruit, has placed in 

 the order MeliaceBe, is not different from Alsodeia, a genus 

 published somewhat earlier, and from more perfect mate- 

 rials, by M. du Petit Thouars,^ who refers it to Violese. 

 The latter generic name ought of course to be adopted, 

 and with a change in the termination {Alsodina) it may 

 also denote the section of this order with regular flowers. 



Thysipliora of Sir Joseph Banks's herbarium, discovered 

 by himself in Brazil, differs from Alsodeia only in its fila- 

 ments being very slightly connected at base, and in the 

 form and texture of its capsule, which is membranaceous, 

 and, as the name imports, inflated. 



Five species belonging to this section of Violese occur in 

 Aublet's History of the Plants of Guiana, where each of [*ii 

 them is considered as forming a separate genus. Of three 

 of these genera, namely, Conohoria, Binorea, and Biana 

 the flowers alone are described ; the two others, Passura 

 and Piparea, were seen in fruit only. 



Prom the examination of flowers of xiublet's original 

 specimens of the three former genera, in Sir Joseph 

 Banks's herbarium, and of the fruit of Conohoria, which 

 entirely agrees with that of Passura, and essentially with 

 that of Piparea, I have hardly a doubt of these five plants, 

 notwithstanding some differences in the disposition of their 

 leaves, actually belonging to one and the same genus ; and 

 as they agree with Physiphora in every respect, except in 

 the texture and form of the capsule, and with the Passalia 

 of Sierra Leone and Congo, except in having their stamina 

 nearly or entirely distinct, it appears that all these genera 

 may be referred to Alsodeia. 



I have also examined, in Sir Joseph Banks's herbarium, 

 a specimen of Pentaloba sessilis of the Plora Cochinchi-
